Vulnerable Systems:
* Adobe Flash Player before 18.0.0.268 and 19.x and 20.x before 20.0.0.228 on Windows and OS X and before 11.2.202.554 on Linux, Adobe AIR before 20.0.0.204, Adobe AIR SDK before 20.0.0.204, and Adobe AIR SDK & Compiler before 20.0.0.204

Immune Systems:
* Adobe Flash Player after 18.0.0.268 and 19.x and 20.x after 20.0.0.228 on Windows and OS X and after 11.2.202.554 on Linux, Adobe AIR after 20.0.0.204, Adobe AIR SDK after 20.0.0.204, and Adobe AIR SDK & Compiler after 20.0.0.204

Adobe Flash Player and AIR are prone to a remote code-execution vulnerability. An attacker can exploit this issue to execute arbitrary code in the context of the user running the affected application. Failed exploit attempts will likely result in denial-of-service conditions.
